I tried searching Zedge, and then just a general search on Google, but I can't find an alarm that I like. I am a super light sleeper and prior to owning my Moto X (2013), my Galaxy S3 would wake me up simply by vibrating on the rug while plugged in across the room. I might end up doing the same thing with the Moto X, but it has a louder, more urgent vibration sound to it. I seriously hate high frequency/urgent noises in my wake up alarm but everything I found (even the ones that claim to be "soft") use very sharp noises.
